The history of the use of composite new materials can be traced back to ancient times. The straw-reinforced clay used since ancient times and the reinforced concrete that has been used for hundreds of years are composed of two materials. In the 1940 s, due to the needs of the aviation industry, glass fiber reinforced plastics (commonly known as FRP) were developed, and the name composite materials appeared. After the 1950 s, high-strength and high-modulus fibers such as carbon fiber, graphite fiber and boron fiber were developed one after another. Aramid fibers and silicon carbide fibers appeared in the 1970 s. These high-strength, high-modulus fibers can be combined with synthetic resins, carbon, graphite, ceramics, rubber and other non-metallic substrates or metal substrates such as aluminum, magnesium, and titanium to form composite materials with their own characteristics. The specific strength of ultra-high molecular weight polyethylene fiber ranks first among all kinds of fibers, especially its excellent resistance to chemical agent erosion and anti-aging performance. It also has excellent high-frequency sonar permeability and seawater corrosion resistance. Many countries have used it to manufacture high-frequency sonar shrouds for ships, which greatly improves the ship's mine detection and mine clearance capabilities. The new composite materials developed by Scarlett New Materials in China represent a higher level in China. In addition to the military field, UHMWPE fiber also has broad application prospects in the fields of automobile manufacturing, shipbuilding, medical equipment, sports equipment and so on. The fiber has aroused great interest and attention of the developed countries in the world.
